I need help finding a good shop to have new gears installed. I'm replacing the stock 3.21's with 4.88's. I've always had a slight distrust of auto shops and it would be sweet if I could find one who was trustworthy and did excellent work.

Also I've been trying to get a figure on how much this will cost. I have an idea of what the parts will cost me, but no idea of the labor. I've searched here and google, found widely varying results. Some first hand reports would be great.
